Abstract: Aqueous carbonaceous mixtures such as water slurries of solid particulate carbonaceous materials having reduced viscosity, a stabilized network of carbonaceous materials in water and improved pumpability are obtained by using a condensation product of an aldehyde in aldehyde liberating composition, ketone and sulfur dioxide in a sulfur dioxide liberating composition as dispersant, the dispersant being present in an amount sufficient to reduce viscosity of the slurry, stabilize the network of carbonaceous materials in water and improve pumpability. An improved process for the condensation product is disclosed.

Abstract: Process for treating a clayey geological formation to prevent, inhibit or reduce swelling or migrating of clay particles in a formation by treating the formation with an effective amount of a quaternized oligomer which is the reaction product of a polyamine having a primary amino group and a tertiary amino group with a difunctional reactant to form a precondensate monomer which is then chain extended and quaternized by reaction with a dihalogenated hydrocarbon ether.A preferred oligomer is a product of:(I) about 1.0 mole of a precondensate which is the reaction product of(A) from about 2.0 to about 3.0 mole of a polyamine having a primary amino group and a tertiary amino group, the polyamine having a non-cyclic backbone containing between 1 and 6 carbon atoms, with(B) about 1.0 mole of a difunctional reactant which is a diester of a mixture of dicarboxylic acids such as adipic, glutaric and succinic acid, with(II) from about 1.0 to about 1.2 mole of a chain extender such as dichloroethylether.

Abstract: A highly efficient formaldehyde-free coating composition insolubilizer is prepared by reacting about 3 moles of glyoxal with 1 mole of urea resulting in a formation of a low molecular weight oligomer in a yield of 95-96%. The molar ratio of glyoxal to urea is very critical in obtaining the highest efficiency and is kept within narrow limits. The coating compositions of the present invention possess 2 till 4 times higher wet-rub resistance than the prior art compositions.
